GSSV Tjas was founded on the initiative of Henk and Gerrit on March 6, 1968. Since 1968 a lot has changed. In the early years they skated in Heerenveen, until 1971. In 1971 the first ice rink was build in Groningen, “IJsstadion Stadspark”. Some amateurs became more and more fanatic, they started competing in competitions. Nowadays a lot of members are competing in several competitions like, IUT’s, NSK’s, regional competitions and of course our own competitions. The name “Tjas” originated on the initiative of Simone Kragt. Tjas-Olmai is one of the several gods the Lappish honor. The name stands for “waterman”. This god stands for lakes and fishing.
